WATCH-PROTECTOR.

Specification of Letters Patent.

Patented Sept. 17, 1912.

' To all whom it may concern:

Be it known that I, JAMES A. FULLER, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented a new and useful Improvement in VVatch-Protectors,of which the following is a specification.

This invention pertains to certain new and useful improvements in watchprotectors, and relates more particularly to a clasp which is connectedto the chain and to the watch and which has points or prongs that areadapted to be brought into engagement with the watch pocket when thechain is subjected to strain.

The object of the invention is to provide a device of this type in whichthe points or prongs are located on the exterior of the clasp so as tobe brought into instantaneous engagement with the watch pocket; andfurther to generally improve, simplify and increase the eflioiency ofdevices of this type.

In the drawings-Figure 1 is aside elevation of the invention. Fig. 2 isa section on the line 2-2 of Fig. 1. Fig. 3 is a section on the line 3-3of Fig. 2. Fig. 4: is a detail perspective view of the slide. Fig. 5 isa similar view of the presser member carried by the slide; and Fig. 6 isa similar view of one of the points or prongs.

The housing 1 has rigidly secured thereto at one end a hook 2, and apivoted spring pressed tongue 3. The opposite end of the housing is openand has the ring 4 of the slide 5 projecting therethrough. The slide 5as depicted in Fig. 4 is hollow and is formed with oppositely disposedinterior shoulders 6 and a contracted yoke portion 7.

Slidingly arranged on the interior of the slide 5 is a presser membercomposed of a body 8 the bottom end of which is concave as indicated at9. Extending upwardly from each side of the body 8 are arms 10 which arespaced apart to receive a spring 11. Shoulders 10 that are formed on thepresser member, normally engage the shoulders 6 of the slide to restrictthe inward movement of the presser member.

A pin 12 extends through the outer end portion of the slide 5 and hasits ends secured to the outer end portion of the housing 1 as depictedin Figs. 2 and 3. The upper end of the spring 11 bears against the pin12 whereby it will be seen that when the slide 5 is moved outwardly thespring 11 will be compressed and will, upon release of the slide, bemoved inwardly.

The points or prongs 13 are disposed on opposite sides of and exteriorlyof the housing 1 and are pivoted by means of pins 15 to cars 14 that areformed on the housing 1. The points or prongs 13 are formed at theirlower ends with bell crank levers 16 which are reduced in thickness andoverlap and project through openings in the sides as depicted in Fig. 2.The inner ends of the bell crank levers 16 are rounded as shown at 17and extend over the curved face 18 of the bottom 19 of yoke 7, and theconcaved end 9 of the presser member engages on top of said rounded ends17 and normally tends to hold the parts in the position shown in fulllines in Fig. 3.

In operation when the slide 5 is moved outwardly the curved face 18 ofthe yoke 7 thereof which engages under the rounded end 17 of the pointsor prongs 13 causes the latter to be moved to the dotted line positionin Fig. 3. Since the presser member engages on the outer sides of theends 17 the latter will be held under tension due to the compression ofthe spring 11, and when the slide is released, the spring 11 will expandand forces the presser member inwardly against the bell crank levers 16,whereby the points or prongs 13 will be returned to the full lineposition in Fig. 3. The arms 10 of the presser member are preferablyconcave at their free ends as indicated at 20 in order to receive thepin 12 in event of excessive outwardmovement of the slide 5.

Having thus described my invention, I

claim as new and desire to secure by Let ters Patent 1. In a device ofthe type set forth, a hollow housing having a hook at one end and havingits opposite end open, a hollow slide in said open end of the housinghaving a yoke at one end and oppositely disposed interior shouldersspaced from the yoke, a pair of prongs pivoted to the casing on theexterior thereof and having bellcrank levers with rounded inner, endswhich extend on the interior of the housing and in the yoke of the slidein overlapping relation with each other, said yoke having the inner faceof its bottom of.convex form to engage the rounded inner ends of thebell cranks, a presser member in the hollow slide having shoulders toengage the shoulders of the slide andhaving its bottom concave to engageon top of the rounded ends of the bell cranks, arms projecting upwardlyfrom the presser member in spaced relation thereto, a pin carried byoverlappingrelation with each other, a hol- 7 low slide in the housingthat engages the outer faces of the bell cranks, and a spring pressedmember inthe interior. of the slide that engages the inner faces of thebell cranks.

3. In combination with a hollow housing, a pair of prongs pivotallysecured on the exterior thereof and having bell crank levers that extendon the interior of the housing, 1

iname to this specificatlon 1n the presence of ;two subscrlblngwitnesses.

a hollow slide in the housing to engage the outer faces of the bellcranks, and spring pressed means in the slide capable of movementindependent thereof to engage the innerfaces of the bell cranks and toengage the housing.

4. In combination with a hollow hous- 111g, prongs pivoted on theexterior thereof, a hollow slide to engage and actuate the prongslocated in the interior of the housing, and means in the slide capableof movement independent thereof to restore the prongs to normalposition, after actuation thereof.

5. In combination with a hollow housing, prongs pivotedon the exteriorthereof, a

hollow slide in the housing to move the jprongs away from the housing,and spring pressed means arranged in the slide and.

capable of movement independent thereof to slide to normal positionafter actuation.

6. In combination with a hollowhousing,

a pair of prongs pivotally connected to the jho-using and having bellcranks that extend gon the interior of the housing, a'hollow slide inthehousing having a bottom the inner In testimony whereof I have signed myJAME S A. FULLER. Vitnesses: v V ADA E. HAGERTY, J. A. MILL R;
